Specific embodiments
[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0027] In the embodiment, it is given by Figures 1-4 a circuit board surface coating device for circuit board production. The present utility model includes a coating table 1, a protective cover 2 is fixedly connected to the top of the coating table 1, a baffle 3 is arranged on the front side of the protective cover 2, moving devices 4 are arranged inside the coating table 1 and on the inner top wall of the protective cover 2, a protective frame 5 is fixedly connected to the outside of the lower moving device 4, a clamping device 6 is arranged inside the protective frame 5, two clamping plates 7 which are symmetrically distributed left and right are fixedly connected to the outside of the clamping device 6, a mounting plate 8 is fixedly connected to the bottom of the upper moving device 4, an electric push rod 9 is fixedly connected to the bottom of the mounting plate 8, and a spraying device 10 is arranged at the bottom of the electric push rod 9.
[0028] Among them, the two moving devices 4 include first motors 41 respectively fixedly connected to the inside of the coating table 1 and the inner top wall of the protective cover 2. Threaded rods 42 are fixedly connected to the outside of the output shafts of the two first motors 41, and first transmission blocks 43 are in threaded transmission connection with the outside of the two threaded rods 42.
[0029] In this embodiment, in actual use, the first motor 41 is started, and the threaded rod 42 rotates. At this time, the first transmission block 43 moves in the horizontal direction under the action of the thread.
[0030] The inner top wall of the coating station 1 and the inner top wall of the protective cover 2 are fixedly connected with sliding rods 11, and the bottom of the protective frame 5 and the top of the mounting plate 8 are fixedly connected with sliders 12 which are slidably connected to the two sliding rods 11 respectively.
[0031] In this embodiment, during actual use, when the first motor 41 drives the protective frame 5 and the mounting plate 8 to move, the slider 12 will also slide outside the sliding rod 11 to stabilize the sliding direction of the protective frame 5 and the mounting plate 8.
[0032] Among them, the clamping device 6 includes a second motor 61 fixedly connected to the inside of the protective frame 5, and the outer side of the output shaft of the second motor 61 is fixedly connected to the left and right screw rods 62 rotatably connected to the inside of the protective frame 5. The outer sides of the left and right screw rods 62 are connected through threaded transmission to two second transmission blocks 63, which are respectively fixedly connected to the two clamps 7.
[0033] In this embodiment, in actual use, after the second motor 61 is started, the left and right screw rods 62 will rotate, and under the action of the threads, the two second transmission blocks 63 drive the two clamping plates 7 to move in the opposite direction.
[0034] A clearance groove is provided inside the baffle plate 3 , and the area of the clearance groove is equal to the side area of the protection frame 5 .
[0035] In this embodiment, during actual use, the baffle 3 is fixed to the outside of the protective cover 2 by fasteners such as locks. When the baffle 3 is fixed, the front side of the protective frame 5 is longer, and the forward and backward movement of the protective frame 5 just passes through the baffle 3 and is blocked by the protective frame 5.
[0036] The top surface heights of the two clamping plates 7 are lower than the top surface height of the protection frame 5 , and a fan 13 is disposed on the inner rear wall of the protection cover 2 .
[0037] In this embodiment, during actual use, when the circuit board is fixed on the clamping plate 7, the height of the clamping plate 7 is lower than the top surface height of the protective frame 5. The fan 13 is an exhaust fan, which can discharge the residual coating agent in the protective cover 2 through the pipe to prevent excessive odor.
[0038] Working principle:
[0039] When coating the circuit board, first fix the baffle 3 to the outside of the protective cover 2. At this time, provide the first motor 41 to move the protective frame 5 out, place the circuit board on the clamping plate 7, and clamp the circuit board by starting the second motor 61. Then, the protective frame 5 is moved into the protective cover 2 by the first motor 41 below. At this time, start the first motor 41 above, and lower the spraying equipment 10 through the electric push rod 9. Move the spraying equipment 10 left and right while spraying the circuit board moving forward and backward, so that the circuit board is sprayed evenly in place. The spraying equipment 10 is connected to the air pump by a connecting pipe, and the stored spray agent is sprayed from the nozzle onto the circuit board by pressure. At this time, the clearance groove is blocked by the protective frame 5, and there will be no splashing to the human body.
